Published Article / Spin casting is widely used as a batch manufacturing process for decorative products. In the process, moulds are filled by taking advantage of the centrifugal effect, which is used to increase the pressure within the moulds, resulting in more detailed products. In this study, we analyse the different parameters that could affect the casting of mechanical parts through spin casting. Through this study, the user will be guided in the selection of parameters that will result in a certain degree of accuracy. The parameters were determined by performing numerous experiments using zinc alloy and tin-based pewter as casting materials. Results were obtained by casting approximately 15 000 parts in various positions, and at various clamping pressures, rotational speeds and temperatures in both the mould and the material. The experiments were undertaken by varying one parameter at a time, and with each set parameter repeated once, resulting in 100 test pieces per parameter for evaluation. From the results obtained, a series of critical factors and parameters, which are driven by part characteristics or features, has been studied. Contrary to following a modelling approach, the research was conducted following an action-research approach, with planned activities, but where actual results have defined the follow-up procedures. These guidelines will help industrial users ensure the accuracy of parts produced by spin casting. Also, since this project attempted to create a database of results that can be applied in future, it furthermore implies that the data created for the first time can be used in a numerical modelling approach in further / follow-up research. No such data was available from any previous research.

Symphony Number 1 for Concert Band is a musical composition for symphonic band. The work calls for an ensemble of large forces in order to explore a variety of musical textures and techniques within traditional formal design. Formally the work is in three independent movements. Each movement is built upon a relatively traditional form or key scheme. The first movement is the most complex, a modified rounded binary form with dominant -- tonic relationships. The second is a passacaglia, and the third is a highly rhythmic sonata rondo. A variety of instrumental textures are explored throughout the work. Climactic sections call for large tuttis and ensemble unisons. Sections for small groups balance these larger statements. Soloists drawn from the ensemble are frequently called for, with the third movement featuring an extended duet for soprano and alto saxophone. Traditional tonal harmonic structures are melded with harmonies driven by polytonal chromaticism in a melodic context. Polytonal chromaticism is a formative element of the work, appearing throughout each movement and used to provide structure and dramatic tension at all levels within the composition. / text
